Long summer is a festival that reflects seasonal changes. Standing is the beginning, summer is the season. According to the traditional understanding, this is the beginning of that summer. Usually on May 5th or 6th of the Gregorian calendar.
On the day of the long summer, the sun moved to 45 degrees of the yellow meridian. At noon, the sun shadow was measured with standard meters, with a length of four inches, three feet and six minutes, which is equivalent to today's 1. 108 meters. Bucket handle, watching the Big Dipper at night, points to the third place, that is, the southeast direction. This stage is usually in April of the lunar calendar, also called Mitsuki, early summer, Huaixia and Xia Meng.
According to the standard of climatology, when the average temperature reaches 22℃ in five days, summer begins. In the middle and lower reaches of the Yellow River, the waiting temperature in the long summer season is close to the climatological standard, which is the origin of the twenty-four solar terms. From this point of view, it is practical to regard the Long Summer Festival as long summer in the 24 solar terms.
Long summer is divided into three stages. "At first, crickets sang." Cricket No.1, also called toad, is a kind of frog. At this time, frogs began to sing in the fields and ponds for food. "Wait for the earthworm to come out", because the underground temperature continues to rise, the earthworm climbs from the underground to the ground to breathe fresh air. "Third-class king melon", also known as sweet potato, has begun to grow and mature. Qing Qianlong's "Xinzheng County Records" contains: "April melons are picked and sold, and they are said to be fresh when given to each other." From these three descriptions, we can see the summer scenery.
